摘要:     本發明係為一種溫度感測電路,其包含一開關電路、一充電電路及一判斷電路。開關電路接收一供應電壓以產生一開關信號。充電電路耦接開關電路且接收供應電壓,開關信號控制充電電路,以依據供應電壓產生一電壓信號。判斷電路耦接充電電路,判斷電路依據電壓信號之位準產生一判斷信號,其中開關信號及電壓信號之位準相關於一溫度狀態,且判斷信號表示溫度狀態。本發明之溫度感測電路可應用於顯示面板之驅動電路,以偵測溫度狀態,而調整驅動電路之驅動信號的位準,以提高顯示面板的畫面品質。     The present invention is related to a temperature sensing circuit and a driving circuit. The temperature sensing circuit comprises a switching circuit, a charging circuit, and a judging circuit. The switching circuit receives a supply voltage for generating a switching signal. The charging circuit is coupled to the switching circuit and receives the supply voltage. The switching signal controls the charging circuit for generating a voltage signal according to the supply voltage. The judging circuit is coupled to the charging circuit for generating a judging signal according to the level of the voltage signal. The levels of the switching signal and the voltage signal are related to a temperature state; and the judging signal represents the temperature state. The temperature sensing circuit can be applied to the driving circuit of a display panel for detecting the temperature state. Hence, the level of the driving signal of the driving circuit can be adjusted for improving the image quality.
